High barrier to rotation about the Pd–N bond in trans-dichloro-dihydrazonepalladium(II) complexes
Abstract
Newly synthesized trans-[PdCl2(R1R2CN1–N2R3R4)2] complexes have a high Pd–N1 rotational barrier which, in solution, gives rise to two isomers depending on the relative orientations of the hydrazone molecules with respect to each other (symmetrical in one isomer and asymmetrical in the other).
